You’ve turned the furnace on earlier than you wished, your golf game got canceled — and you’re already eyeing a new sweater.

If it gives you any comfort, you’ve been through the coldest start to October on record.

Regional offices of the National Weather Service crunched the numbers Thursday. They found that the combined average daytime-nighttime temperature in the first 14 days of the month was an astonishing 12 to 15 degrees below normal.

That’s based on records dating back from 50 to more than 100 years, depending on the time period evaluated by each office.
